MENS *FOR FORMING LEAD WIEE.

T0 all whom t may concern:

Be it known that I, ADAM TUnoR Errori,

- tion of carbonate of lead, the white lead of commerce. p p Y ln thisprocess for the production'of white lead it is desirable that as large asurface as possible ot' the metal be exposed to the corroding agents,and these surfaces should be such as will not pack closely in contactwith lone another. A finely drawn lead wire has been found to be themost effective, and it is to produce this lead wire in a yrapid andcheap manner with an inexpensive plant that the device which is thesubject of this application, has been devised. l

rlhe invention is particularly described in the following specification,reference being.

made to the drawings by which itis accompanied, in which:

Figure l is a longitudinal section through the apparatus complete, andFig. 2 is a perspective and part section of the lead delivery tumt orhopper.

In these drawings 2 represents a hemispherical lead melting pot which issuitably supported over a furnace 3, or other means isprovided by whichthe lead may be maintained in a molten state. ln the lower part of thismelting pot is a delivery aperture 4 which is -`closable by means of avalve 5 and connected'to this aperture 4 is a pipe 6 delivering outsidethe wall of the furnace into a channel 7 having a removable cover toprevent oxidation. rThis channel 7 delivers into a tumlit or hopper 9which is rectangular in plan and in cross section is the rustum of awedge; and along the bottom of this tumfit is a line of small apertures10 through which .the molten lead pours in a series of smallSpecification of Lettersl Patent.

l2 in which water may be maintained at a substantially constant, levelabout one inch below the outlet apertures 10. Immediately below theseoutlet apertures an endless traveling band '13 of canvas' or the like ismovable over a driving pulley 14, which band passes over a pulley 15 atthe other end of the tank and delivers on to an inclined chute 16. z.Thelower endof this band is below theA surface of the water and the upperend above the level of the upper edge of the tank. 0n to this endlessband 13 the lead Hows from the apertures 10 of the tumit in a series ofsmall-streams which are supericially set as they fall intoithe water, so

that they are substantially circular in cross section; but as they fallon the band the ,velocity of which is slightly greater than the velocityof the issuing streams the lead is attenuated or/drawn out, according tothe speed at which the endless band moves,.and as a result the lead isdelivered to the chute as a finely drawn wire.

The driving pulley of the endless band is preferably below the tumfit asby thatmeans variation in the rate of travel of the bandl most effectivefor the purpose fo`r which the device has been particularly designed; Ido not desire to be confined to such, as a wire or ribbon of any desiredcross section and of other material than lead may be produced by thesame means. `1` f Havin now articularly described m in vention, here ydeclare that what I c aim as new and desire to be protected in byLetters Patent, is:

l. Means for producing a finely divided wire of lead, said meanscomprising the combination with a melting pot, of a hopper havingaseries of small apertures in the bottom into which hopper the moltenmetal is deliveredfan endless traveling band,ar

ranged beneath the hopper apertures to receive the metal and a reservoirin which said band projects, a cooling fluidv in said reservoir, thecooling fluid emersing said band at the place oi, saidl hopper dischargewhereby the molten metal from the hopper passes through the cooling iuidjust prior to the delivery of the metal on to the travel ing band tocause the metal to be partially surface cooled.

2. Means for producing a inelydivided Wire of lead, said meanscomprisingthe combination With a melting pot.y having an outiiow aperture adjacentto the bottom, and

means for regulating the How of the moltenv metal therethrough, a ductconveying the molten metal from the outflow aperture of vthe melting potto a tumfit having a line of small apertures in the bottom, meansadjacent to the outliow apertures of the turnit for maintaining themetal in a liquid condition, and an endless traveling band beneath theapertures of the tumt which hand is traveling faster than the outiowingmetal, and means for imparting a primary surface cooling to the metal asit leaves the tumit and for rapidly cooling the metal as it is deliveredonto 'the traveling band.

3. Means for producing a inel,l divided Wire of lead, said meanscomprising the cornbination with a melting pot having an apervtureadjacent to the loottom, and means for regulating the iovv of the moltenmetal through that aperture, of a ductoonveyin'g the molten lead to atumiit having a line of small apertures in the bottom, said tumitsupported over the level of Water in a trough and an endless travelingband inclined 11pv less traveling band, means for delivering the moltenlead upon said traveling band, means for directing said traveling bandfaster than the movement of the stream of lead, and means for surfacecooling the stream of lead prior to its Contact With the traveling band.l
